Abstract This paper shows that by combining electrical fault isolation and characterization by microprobing with physical fault isolation techniques both what is wrong with the circuit and where the defect is located can be determined with less microprobing and more safety from electrical recovery. In the first example, the unit was powered up using the optical beam induced resistance change (OBIRCH) supply, and OBIRCH was performed to determine if there were OBIRCH site differences between the good part and the return. The second example uses a combination of electrical fault isolation and characterization with microprobing and the physical fault isolation tool of lock in thermography (LIT). With these two examples, it has been shown that the use of electrical fault isolation and microprobing can be used to enhance the physical fault isolation tools of OBIRCH and LIT.

Defect Localization

Abstract Equipment manufacturers have developed peripherals for their tools that add soft defect localization (SDL) capability to existing optical beam tools, in many cases providing excellent results. However, these upgrades add significant cost to the tool. This paper presents the design considerations for a simple adapter that was developed in house to add SDL capability to optical beam induced resistance change (OBIRCH) tool, including resolution of some unexpected problems. This solution represents a simple, low cost method to add SDL testing capability to the OBIRCH tool and can also be used in conjunction with OBIC and XIVA tools with little or no modification. An early example of the SDL results provided by this adapter is also presented.

Abstract With decreasing transistor sizes accurate failure localization becomes more and more important in order to find the root cause of failures with high efficiency. Field returns are a special challenge, since there is usually only one sample for preparation. Hence, reliable high resolution localization is mandatory for a successful preparation. Optical beam induced resistance change (OBIRCH) is a powerful tool for localization but has resolution limitations due to the diameter of the optical beam. The tool can be further improved by the lock-in technique. In this paper we demonstrate that the lock-in technique can also be applied for electron beam localization methods like electron beam induced current (EBIC) / electron beam absorbed current (EBAC) and resistance change imaging (RCI) / electron beam induced resistance change (EBIRCH).
